It's probably nice, but the social media tie-ins kill it for me.

Cheers,

Cheers,

If you mean the Google /Facebook login then that's actually becoming more common, bit more secure. It's easy to set up a Google account with zero of your personal details just for things like this, easier for you as well with less passwords to remember. Just takes a few minutes

Maybe a silly question. I know passageweather since quite a long time and was using it until 2 years ago.
Checked back and could not see the difference.
What is new?

This thread was started when passageweather was brand new.

i found it most useful and handy for predicion of named storms and tracking. windy ty didnt cut it, but passage did the job. i use 3 -4 other sites as well, never windy ty--their predictions are insane on windy ty. hurricanes to san francisco?? wak. passage weather is much more accurate. especailly for west coast and predicting named storm tracking.

Zee, when did you see a San Francisco hurricane on windytv.com? This would really surprise me, since windytv uses the same GRIB data as most other sites (GFS, NAM, and ECMWF). The user interface and windspeed colors are perhaps different, but not the actual data they show you.

at 2 separate times while tracking potential threats to us here in caneville 2015 saw the windy ty site showing the track all the way to lost angeles and one all the way to san francisco.was early in the year, and i ditched windy ty as any kind of reliability is fake and delusional.
passage weather has not yet let me down nor shown any tracks out of normal cane region. no thankyou--you use windy ty--i will use legitimate an dgovt sites as i have been using for my tracking. thanks but no thanks.
i will stick with my govt sites and storm 2k. nothing like a good rabid storm tracker forum to find best sites for reliable predictions.

It is really silly to talk about the predictive difference between sites that use the same raw model data and just display it differently.

[robert sailor]

Yup, there are just two sources for all the free bee weather sites, European grib files and the American gribs, on windyty you can choose either and compare them... on some just the American GSF gribs. Some feel the European one is better because it's newer, it's just raw data and if you desire something more accurate then a Meteorologist needs to interpret it...and that's never free.

PassageWeather.com does not display detailed data for the Marianas, so we rely primarily on Windguru for advanced planning and the Joint Typhoon Warning Center for storm tracking. Windytv.com is good for determining larger weather patterns, esp. high and low pressure areas and interfaces, but lacks as a planning tool.

[zeehag]

many models --about 4-5 are close to actually accurate. in event of named storms, 2-3 are semi accurate and one is dead on. that one last year was euro. oops. year before was a different model ....
hhhmmmm..
isnt it good we have more than one source of info so we do not have to be caught in a major event

They seem to show detailed I'm not there so I don't know how detailed and accurate but
Found it on the low bandwidth download for the south china sea

As we're not in the South China Sea, the only region shown that includes us is the greater Northern Pacific, which is very low resolution.

Regional variations here can be significant; a difference of wind velocity of 10-20kts for an increase of ~3 degrees latitude is common. Windguru provides precise granular forecasts for specific latitudes and in our experience, is very accurate. Windytv provides good information about pressure systems and likewise, allows for viewing regional trends.

Yoy must be north east of guam then and I agree that the big picture doesnt help much with local variations.

I have been comparing Passageweather's proprietary PWE GRIBS with GFS for my area and find that, while they usually agree pretty well, when they differ the GFS tends to be more accurate. While bashing back to SoCal from Cabo last spring I compared GFS, USN and the European models and, again, found that GFS was slightly more accurate.
